Hey rbray89, Thanks for the reply. I actually downloaded, installed, re-installed, deleted, rinsed and repeated many times. I did get it to work after searching some more and trying a bunch of different combinations. I'm working with Clouds & City Lights Lo-Res, 2K textures, and Universe Replacer, Seems I couldn't use 8K even with a machine from 2013... doh (haven't tried 4K yet). Although Duna's "clouds" appear red no matter what I try! very annoying. Any suggestions? Best, Avi
